Installation
Grounding
System Connections
• Install each pumping unit with a high pressure check
valve in the discharge line adjacent to the pump dis-
charge connection so that pump assembly may be
removed from reservoir without loss of lubricant in
lines (F
IG
. 1).
• Install a second of these valves at the point of lubri-
cation to prevent line drainage and feedback of sys-
tem pressure to pump (F
IG
. 1).
Drive Mechanism
A 1-1/4 inch diameter shaft is provided to connect the
lubricator to a rotary power source. A woodruff key and
key way on the shaft are provided to aid in connecting
this source.
Install protective guards around all drive components.
Operation
Oil Level
1. Remove vent plugs (A) located on the top of the
pump sight glasses to allow lubricant to rise in the
drip tube to the level of the oil in the reservoir and
reduce the priming required at start up (F
IG
. 2).
2. Completely fill the lubricator reservoir with clean fil-
tered lubricant.
NOTICE
All installation, maintenance, and repair work must be
completed by qualified personnel.
The equipment must be grounded to reduce the risk of
static sparking. Static sparking can cause fumes to
ignite or explode. Grounding provides and escape
wire for the electric current.
